BURNER FLAME PATTERN
Figure 31 shows a correct burner ame pattern. Figure 32 shows an incorrect burner ame
pattern. If burner ame pattern is incorrect then:
• turn heater off (see To Turn Off Gas to Appliance, page 21).
• see Troubleshooting pages 26 through 29.
BURNER PRIMARY AIR HOLES
Air is drawn into the burner through the holes in the tting at the entrance to the burner. These
holes may become blocked with dust or lint. Periodically inspect these holes for any blockage
and clean as necessary. Blocked air holes will create soot.
INSPECTING BURNERS
IMPORTANT: Owner’s should check pilot ame pattern and burner ame pattern often.
Incorrect ame patterns indicate the need for cleaning (see Care and Maintenance,
page 25) or service.
WARNING: Only a qualied service person should service and
repair heater. This includes maintenance requiring replacement or
alteration of components.
PILOT FLAME PATTERN
Figure 29 - Correct Pilot Flame Pattern
(Natural Gas shown)
Figure 30 - Incorrect Pilot Flame Pattern
(Natural Gas shown)
Figure 29 shows a correct pilot ame pattern.
Figure 30 shows an incorrect pilot ame pat-
tern. The incorrect pilot ame is not touching
the thermocouple. This will cause the ther-
mocouple to cool, which shuts the heater off.
If pilot ame pattern is incorrect, as shown
in Figure 30
• turn heater off (see To Turn Off Gas to Ap-
pliance, page 21)
• see Troubleshooting pages 26 through 29.
WARNING: If yellow tipping
occurs, your heater could pro-
duce increased levels of carbon
monoxide. If the burner ame
pattern shows yellow tipping,
follow instructions at bottom of
this page.
Notice: Do not mistake orange ames with
yellow tipping. Dirt or other ne particles enter
the heater and burn causing brief patches of
orange ame.
